"Silver Angel" S Series Printed Circuit Board Welded Power Transformer

The standout feature of the "Silver Angel" S Series closed epoxy pot-sealed tune-source transformer is its excellent electromagnetic characteristics and high input overcurrent ratio, with a total capacity that can reach up to 275V. It demonstrates wide environmental adaptability and superior safety performance. The internal temperature protection device effectively cuts off the power supply in the event of a short circuit, preventing equipment burnout. This makes it the ideal choice for customers producing industrial-grade and military-grade equipment. The robust casing is made from silver-gray flame-retardant PBT and PBO engineering plastic. Due to its outstanding performance, it has earned the nickname "Silver Battle."

    Features

    ① The fully-encapsulated printed circuit board is able to be directly welded and assembled, making it easy to use with a perfect outline.
    ② It is compact in structure, solid, vibration-proof, moisture-proof, flame-resistant, and has high dielectric strength.
    ③ It has low idle current, high power factor, and good over input voltage capacity.
    ④ Compared with the T Series, it has higher reliability and better adaptability to the environment.
    ⑤ It has a built-in temperature protector, making it safer to use.

    Ambient Conditions

    ① Ambient temperature:-25℃~+70℃;
    ② Relative humidity:≤90% at 40℃;
    ③ Atmospheric pressure:860~1060mbar
    (650~800mmHg approximately).

    Insulation Rating

    Class F (155℃).

    Safety Features

    ① Dielectric resistance: >1000MΩ in normal condition;
    ② Insulation withstand voltages: 3750V (50HZ)/1 min;
    ③ Insulation impact strength: Continuously 20 times impact of 6KV (50HZ)/50μS;
    ④ Fire retardancy: In conformity with UL94-Vo;
